To all whom/ 251'? 71'MLZ/ concern:

Be it known that I, LEWIS KUGHENBEGKER, a citizen of the United States,residing at Waltham, 1n the county of Mower and State of Minnesota, haveinvented certain new and useful Improvements in Vehicle Seats, 01' whichthe following is a specification.

The invention relates to an improvement in spring supports for vehicleseats designed primarily to prevent transmission of the usual vibrationof the vehicle-body to the person occupying the seat.

The main object of the present invention is to provide a spring-supportwhich in use provides for a cushioned independent rocking of the seat toavoid transmitting to the occupant the jars and vibrations incident tothe ordinary movement of the vehicle, the construction providing forcushioning the movement of the seat in both directions.

The invention will be described in the fol lowing specification,reference being had particularly to the accompanying drawings, in whichFigure 1 is a longitudinal central section through the vehicle-body,showing the seat thereof supported by my improved springsupport. Fig. 2is a transverse section of the same. Fig. 3 is a perspective of one ofthe spring-cups.

Referring to the drawings, 1 represents a vehiclebody, and 2 the seattherefor, both of which parts, so far as the present invention isconcerned, may be of any preferred con struction.

Secured to the bottom strips 3 of the ve hicle body are inverted-Ushaped framebars 4, cross-bars 5 of which occupya positionlongitudinally of the vehicle-body and some distance above the bottomthereof. Seatstrips 6 are secured to and beneath the side cleats of theseat, being respectively arranged when the seat is properly positionedin alinement with the cross-bars 5 of the respective frames 4. Theseat-strips and frames 4 are pivotally connected through the medium ofarms 7, formed at their upper ends with eyes 8 to snugly receive-thestrips 6, bolts or other fastenings 9 serving to the arms relative tosaid strips. A frame member 10 is formed to snugly embrace the cross-bar5 of the frame and extended vertically therefrom to provide spacedparallel arms 11, between which is received the arms 7, a pivot-pin 12forming the medium of connection and uniting the parts to permitindependent rocking movement of the seat, as will be obvious. Brace-bars13, secured at their upper ends upon the pivot-pins 12, extend at anangle toward the bottom of the vehicle-body and are secured to acrossbrace strap 14,which is terminally secured to the bottom strips 3.The bracket member 10 is secured in fixed relation to the cross-bar 5through the medium of a fastening means 15, and said bracket members andarms 7 are preferably arranged centrally of the frame 4 and strips 6,whereby to provide for a uniform movement of the seat.

The seat is cushioned in its rocking movement through the medium ofsprings 16 and 17, arranged for cooperation with each strip 6 at frame4, the former being arranged in advance of the pivotal connection andthe latter in rear thereof. The ends of the springs are secured incontact with the strips 6 and crossbars 5, respectively, through. themedium of cups 18 and 19, the former securing the lower ends of thesprings to the cross-bars 5, While the latter secures the upper endsthereof to the strips 6. The cups 18 and 19 are identical inconstruction eXce t that the latter has a somewhat-longer shan (1 01 apurpose which will later appear. Each of the cups is provided with aperipheral flange 20, interrupted at determinate points to provide aseries of flexible lips, designed to be slightly bent inward after theinsertion of the adjacent coil of the s ring therein to overlie saidcoil and retain t e spring in place. A shank 21 projects from each cup.being designed in the case of the cups 18 to be passed through thecross-bars 5 of the frames 4 and be secured thereto through the mediumof nuts 22, the cup proper, of course, resting upon the upper side ofeach cross-bar in position to receive the lower end of the spring. Thestem 21 of the upper cups 19 is passed through the strips 6, with thecup resting against the lower side of said strips in position to receivethe upper ends of the spring. Immediately above the strip the spring 2].is engaged by a nut 23, securing the cup to the strip, the-remainder ofthe stem 21 passing through the side cleats of the seat and through thebottom board 24 of the seat, being secured therebeyond by a nut 25. Theupper cups are thus secured to the strips and to the material of theseat,

providing for a secure fastening for the cups. The springs are securedin place as described,

it being understood, of course, that the respective cups for any onespring are arranged in alinement to normally maintain the spring inproper position for service.

The side cleats of the seat proper are preferably of a single strip ofmaterial, in which event, of course, the strip is to be suitablyrecessed or cut away to permit the use of the fastening means 9 and 22,as will be apparent from Fig. 1.

In use any vibration of the vehicle-body incident to the use of thevehicle will cause a rocking movement of the seat on its pivot pin 12,which movement is cushioned in both directions by the springs 16 and 17.The use of the cups 18 and 19 provides for the ready insertion orrenewal of the springs without material effort and further provides forthe use of the ordinary coil-spring without particular formation topermit its connection in the desired relation, By the use of thebrace-bars 13, arranged to directly support the pivots 12, any tendencyto lateral movement of the parts is prevented, and I am thereby enabledto make these parts of lighter material than would be otherwisepossible.

The device described provides a simple and practical construction in theuse of which vibration or jar incident to the travel of the vehicle-bodyis compensated for and its transmission to the occupant of the seat isavoided, whereby provision is made for easy riding under practically allconditions of road-bed.

While preferring that the cups 18 and 19 be secured to the strips andcross-bars in a manner described, it is obvious that they may be withoutchanging the material results of the invention welded to or cast withsaid frame-bars, and I contemplate such construction as within thespirit and scope of the present invention.

7 Having thus described the invention, what is claimed as new is 1. Thecombination with a vehicle-body and a seat therefor, of a frame securedto the body, a frame member secured to the frame, an arm secured to anddepending from the seat and 'pivotally connected to the frame member,cups secured to the frame and to the seat in front and in rear of saidconnection, and springs removably seated in the cups.

2. The combination with a vehicle-body and a seat therefor, of a framesecured to the body, a frame member secured to the frame, an arm securedto and depending from the seat and pivotally connected to the framemember, cups secured to the frame and to the seat in front and in rearof said connection, springs removably seated in the cups, and bracesconnecting said frame members and vehicle-body.

' 3. The combination with a vehicle-body and a seat therefor, of a framesecured to the body, bracket members secured to the frame, stripssecured to the seat, arms secured to the strips and having pivotalconnection with the frame members, cups secured to the strips in frontand in rear of the arms, cups secured to the frame in front and in rearof the framemember, and springs seated in the respective alined cups.

4. The combination with a vehicle-body and a seat therefor, of a framesecured to the body, bracket members secured to the frame, stripssecured to the seat, arms secured to the strips and having pivotalconnection with the frame members, cups secured to the strips in frontand in rear of the arms, cups secured to the frame in front and in rearof the frame member, and springs seated in the respective alined cups,each of said cups having an interrupted peripheral flange to provideflexible lips to engage the end coil of the spring.

In testimony whereof I afIiX my signature in presence of two witnesses.
